CPL-01 in the Management of Postoperative Pain After Bunionectomy

After signing informed consent, subjects will be randomly assigned to receive study drug (either Investigational product, positive control, or negative control) during unilateral distal bunionectomy with osteotomy. Subjects will then remain at the hospital for 72-hours where pain and rescue medication usage will be assessed. Follow-up will then occur at 7 and 30 days afterwards.

The hypothesis is that subjects who receive CPL-01 will have less pain and require fewer opioids than subjects in the other two arms.

Inclusion criteria

• If biologically male, either sterile or using acceptable form of birth control
• Be willing and able to complete study procedures

• Has a planned concurrent surgical procedure
• Has a concurrent painful condition that may require analgesic treatment during the study period or may confound postsurgical pain assessments
• Has a history or clinical manifestation of significant medical, neuropsychiatric, or other condition that could preclude or impair study participation or interfere with study assessments.
• Has a history of malignant hyperthermia or glucose-6-phosphate dehydrogenase deficiency.
• Has history or evidence of impaired liver function (e.g., alanine aminotransferase [ALT] > 3 × upper limit of normal [ULN] or total bilirubin > 2 × ULN), active hepatic disease, or cirrhosis.
